Eugene, Ore. -- Nearly 11 months after his two missed field goals cost Stanford a Fiesta Bowl win, Jordan Williamson came through in a game that probably means a lot more to the Cardinal and their fans.

He booted a 37-yard field goal in overtime, and 14th-ranked Stanford shocked No. 1 Oregon 17-14 Saturday night and sent the top echelon of college football into more turmoil.

A week after Texas A&M shocked previous No. 1 Alabama, both Oregon and Kansas State went down, probably opening the way for Notre Dame to take the top spot in the polls and the BCS.

It took a yeoman defensive effort by Stanford (9-2, 7-1 Pac-12) to knock off the Ducks (10-1, 7-1) and put itself in position to win the Pac-12 North Division next week by beating UCLA at the Rose Bowl.

Despite giving up two fumbles and an interception, Stanford was able to tie the game on a 10-yard touchdown pass from Kevin Hogan to tight end Zach Ertz with 1:35 left. The play was originally ruled an incomplete pass, but the ruling was overturned on a replay review.

"Our kids keep fighting," coach David Shaw said. "They keep fighting all the way to the end. We knew if we got into the fourth quarter, we'd give ourselves a chance to win. That's what our guys did."

The Ducks had scored 40 or more points in 13 straight games, the longest such streak in the Bowl Championship Series era. Stanford, however, turned the game into a defensive struggle.

That was the break Stanford needed. And they caught still another one when Hogan fumbled but Stanford recovered. Two plays later, Williamson came on.

He said he had visualized the kick going through the uprights "a good 20 times before I went out there." When he made the kick, he happily ran to the other end of the field, with his teammates in joyful pursuit.

"I felt bad because everyone else was running their butts off during the game," Williamson said with a laugh. "I might as well get a workout."

Asked if the kick atoned for the three missed field goals against Oklahoma State in last season's Fiesta Bowl, including two at the end, he said, "It definitely helps, I'll say that."

Hogan, making his second collegiate start, completed 25 of 36 passes for 211 yards and a touchdown, with one interception. He outdueled Marcus Mariota, his fellow redshirt freshman, who completed 21 of 37 for 207 yards and a touchdown.

Speedy Oregon tailback De'Anthony Thomas bolted up the middle for a 6-yard touchdown in the third quarter to give Oregon its first lead at 14-7.

The play climaxed a 95-yard drive that contained five Mariota completions, a near-interception by Trent Murphy and a leg-whipping penalty against the Ducks on which the officials momentarily lost track of the downs.

Hogan scored on a 1-yard run in the second quarter as the Ducks' defense took away his intended receiver, Stepfan Taylor. Mariota threw a 28-yard touchdown pass to Keanon Lowe later in the quarter to tie it.

After the Thomas touchdown, most of the crowd of 58,792 at Autzen Stadium was bracing for the usual Ducks onslaught. It never came.

"Two years ago we were in the same spot at halftime," Ertz said. "In the third and fourth quarters, they killed us. This time we came out strong in the second half."

His tying TD catch was an acrobatic move on his way to a game-high 11 catches for 106 yards. He made a leaping grab and got both feet down, but bobbled the ball off cornerback Ifo Ekpre-Olomu before regaining possession as he landed on top of the Oregon player.

Shaw credited defensive coordinator Derek Mason for orchestrating a shutdown - when it counted - of the nation's highest-scoring offense.

"You didn't see any of those long runs go for touchdowns," Shaw said. "That's something we addressed the last two years in our recruiting. We are faster on the back end. We've got speed."
